/*

|
* This example defines two groups of roles any user/group can be assigned to.
|
|
* An "admin" role which grants full access to all APIs on all objects to its
|
|
* members, and other roles which allows their members to all APIs defined in
|
|
* restrictedActions on domains matching a regular expressions assigned to
|
|
* each role. (Jump below the Role class definition to see them.) Users who
|
|
* belong to an "operator" role can act on any domain (matching ".*" RE),
|
|
* while members of "userA", "userB", and "userC" roles are limited by more
|
|
* specific REs.
|
|
*
|
|
* A virtualization host admin would define domains with names prefixed by
|
|
* customer names and create a separate role for each customer restricting
|
|
* its members to manage only domains with the corresponding prefix.
